GETTYSBURG, Pa. (WHTM) – Democratic presidential candidate Bernie Sanders drummed up support for his campaign during a town hall event before an estimated crowd of 2,400 people Friday at Gettysburg College.

In a one-on-one interview with ABC27 News, Sanders answered a few questions submitted by our viewers. Tom Harvey wanted to know how Sanders would keep diplomacy in the Middle East.

“Well, Tom should know I voted against the war in Iraq, voted against the Gulf War, and I believe military force is the last option, not the first option,” he said. “We have been too much into regime change without thinking through the consequences.”

“We pay for free public schools right now, which go through kindergarten through 12th grade. I believe that the world has changed, the economy has changed, and people simply need more education in a highly competitive global economy,” Sanders said. “That means that we should do what many other countries around the world are doing, and that is making public colleges and universities tuition-free. This is paid for not by the general population, but by a tax on Wall Street. I’m sure you remember we bailed out Wall Street. In my view, it is Wall Street’s turn to help the middle class.”
